multi-information display
The system may be temporarily unavailable
or may be malfunctioning.LTA (Lane Tracing Assist)
When driving on highways and
freeways with white (yellow) lane
lines, this function alerts the driver
when the vehicle might depart from
its lane or course
* and provides
assistance by operating the steer-
ing wheel to keep the vehicle in its
lane or course
*. Furthermore, the
system provides steering assistance
when dynamic radar cruise control
with full-speed range is operating
to keep the vehicle in its lane and
when changing lanes (vehicles with
Lexus Safety System + A).
The LTA system recognizes white
(yellow) lane lines or a course
*
using the front camera. Addition-
ally, it detects preceding and sur-
rounding vehicles (vehicles with
Lexus Safety System + A) using the
front camera and radar.
*: Boundary between asphalt and the side of the road, such as grass, soil, or
a curb

■Lane departure alert function
When the system determines that the
vehicle might depart from its lane or
course
*, a warning is displayed on the

ing wheel will vibrate to alert the driver.
When the warning buzzer sounds or
the steering wheel vibrates, check the
area around your vehicle and carefully
operate the steering wheel to move the
vehicle back to the center of the lane.
When the system determines that the
vehicle might depart from its lane and
that the possibility of a collision with an
overtaking vehicle in the adjacent lane
is high, the lane departure alert will
operate even if the turn signals are
operating.
*: Boundary between asphalt and the side of the road, such as grass, soil, or a curb

Driving
 Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
• Engine/power control unit coolant
•Washer fluid
Have a service technician inspect
the condition of the 12-volt battery.
 Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the rear tires.
*
Ensure that all tires are the specified size
and brand, and that chains match the size
of the tires.
*: Tire chains cannot be mounted on vehi-
cles with front and rear tires of differing
sizes.
Winter driving tips
Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate

Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.

limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower.
●Avoid driving on bumpy road surfaces
or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.

Maintenance and care
■Brake caliper coating (F SPORT mod-
els)
●When using detergent, use neutral deter-
gent. Do not use hard brushes or abra-
sive cleaners, as they will damage the
coating.
●Do not use detergent on the brake cali-
pers when they are hot.
●Wash detergent off immediately after
use.
■Bumpers and side moldings

●The following precautions can extend the
effectiveness of the water-repellent coat-
ing.
• Remove any dirt, etc. from the front side
windows regularly.
• Do not allow dirt and dust to accumulate on the windows for a long period.
Clean the windows with a soft, damp
cloth as soon as possible.
• Do not use wax or glass cleaners that
contain abrasives when cleaning the win-
dows.
• Do not use any metallic objects to
remove condensation build up.
●When the water-repellent performance
has become insufficie nt, the coating can
be repaired. Contact your Lexus dealer.
■Plated portions
If dirt cannot be removed, clean the parts as
follows:
●Use a soft cloth dampened with an
approximately 5% solution of neutral
detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to
remove any remaining moisture.
●To remove oily deposits, use alcohol wet
wipes or a similar product.

Do not apply water to the inside of the
engine compartment. Doing so may
cause the electrical components, etc. to
catch fire.
■When cleaning the windshield
Set the wiper switch to off.

●When a wet rag or similar is held close
to the raindrop sensor
●If something bumps against the wind-
shield
●If you directly touch the raindrop sen-
sor body or if something bumps into
the raindrop sensor
■Precautions regarding the exhaust
